DRP NB 150523: Will the govt listen to caveats against Ken Betwa Project?

May 15, 2023May 15, 2023 SANDRPLeave a comment

The following report raises three caveats regarding Ken Betwa River Link Project, among others. Firstly it urges that the substantial impact of climate change on the rivers needs to be taken into account, particularly the need for accurate hydrological assessment. It underlines that the project themselves are accelerating the climate change impact on monsoons as they are reducing freshwater flows to the oceans, which in turn has an impact on the ocean’s thermal and salinity gradients, both of which are drivers of monsoon.

Secondly, it rightly says that the impact of projects on adaptive capacity of areas like Bundelkhand needs to be taken into account. In Bundelkhand, climate adaptation can be harnessed using rain water harvesting, rejuvenation of traditional water systems, less water intensive crops and alternative agricultural practices. Thirdly, the water sharing issues that may worsen with both climate change and big projects, need to be kept in mind while taking up mega projects, particularly its impact on water and other security issues.

This well substantiated report from Yale School of Environment this week shows that the end of the big dam era is approaching. The well argued report from Jacques Leslie uses the reports from UN University, International Renewable Energy Agency, Oxford University, Inclusive Development International, China, among others to show how the pace of construction of dams and hydropower projects and also pace of financing such projects have hugely reduced in recent years and decades.

Even the International Hydropower Association, sensing the change, is now advocating pump storage hydro rather than conventional hydro and that too off stream version, to complement the power from solar and wind. Emerging economics with rising cost of hydropower projects and rising cost of power from such projects compared to solar, wind (onshore and offshore) are a major reason for the massively slowing pace of new hydropower projects.

That India’s track record in water pollution control is abysmal is self-evident. This is particularly important to note as India prepares to mark 50 years of Water Pollution Control Act enacted in 1974, next year. It was after that act that the huge institutional architecture of central and state pollution control boards and laboratories were created with huge bureaucracy. That whole institutional architecture is more known for inefficiency and corruption than for achieving any clean rivers or cleaning other water bodies. During the existence of this act the bureaucracy that came with it, the state of our rivers and water bodies have only gone worse with every passing year.

DRP NB 130223: El Nino set to endanger 2023 SW Monsoon rains

February 13, 2023February 13, 2023 SANDRPLeave a comment

After four years (SW Monsoons of 2019 [110.4%], 2020 [108.74% compared to normal rainfall], 2021 [99.3% or almost normal rainfall], 2022 [106.5%]) of normal or surplus monsoon rainfall, SW Monsoon 2023 could face rainfall deficit and uncertainties as per US Govt weather agency NOAA and also India’s IMD. El Nino conditions are many times associated with poor monsoon rainfall in India. Since SW Monsoon provides more than 75% of total annual rainfall of India, this can be critical for India. The shift from particularly prolonged La Nina conditions to El Nino conditions should be a warning sign for India. IMD DG has said that the department will come out with an update on Feb 28, which should be sufficient advance notice to take necessary steps to tackle its possible impacts on upcoming Summer and SW Monsoon. We hope the government is ready to take the necessary steps to tackle any eventuality.

DRP NB 060223: Wetlands in India face damages, threats and Govt Apathy

February 6, 2023February 6, 2023 SANDRPLeave a comment

(Feature Image:-Nayapakkam a lake near Chennai and a bird hotspot. 190 species have been recorded here and is a refuge for migratory harriers. https://ebird.org/hotspot/L3396760 Excavators were filling one end of the lake yesterday. Allegedly the ACS group is building an International school over it. M Yuvan, 05 Feb. 2023)

On the occasion of World Wetlands Day 2023 on Feb 2, 2023, SANDRP brought out five overviews about state of India’s wetlands. These included overview related to: 1. India’s Ramsar Wetlands 2. General overview of India’s wetlands 3. Top Ten stories about govt actions about wetlands 4. Top ten stories about judiciary actions about wetlands and 5. Positive stories about India’s wetlands. The links to the five overviews are available below.

The first thing that strikes from these overviews is that state of wetlands in India is bad, getting worse, they continue to face systemic neglect, damages, threats and govt apathy including Ramsar wetlands, which are supposed to have better protection than other wetlands, which is unfortunately not true. The nameplate of Ramsar wetland has now been given to 75 wetlands, but that provides no additional protection to them. in the name of information of Ramsar sites, there is only a combined interactive map apart from two separate pdf file links with location map and state wise listing Ramsar wetlands on Wetlands of India portal by MoEF&CC. The govt has neither prepared any concrete plan to address the threats nor has it developed credible monitoring mechanism which clearly shows it has no intention to improve the governance of these sites.

DRP NB 9 May 2022: Forensic Team report: Michigan 2020 Dams failures were preventable

May 9, 2022May 16, 2022 SANDRPLeave a comment

A Forensic engineering Team appointed by the USA’s Federal Energy Regulatory Commission post the May 19, 2020 failure of Edinville and Sanford Dams in Michigan state of USA has published a 502 page comprehensive report on the dam failure within less than two years of the disaster. The full report published on May 4, 2022 is in public domain and has concluded that the dam failures were foreseeable and preventable.

There are a number of things we can learn from this. Firstly that there are such credible independent assessment of dam failures, we have none in India even after multiple dam failures each year. Secondly, such assessments are promptly in public domain. Thirdly, the reports are completed in less then two years. We have none of these. Even the Dam Safety Act passed by the parliament does not have provisions for any of these.

There are a lot of implications for India here. It means for example that we will never know the real reasons for the dam related disasters. Secondly, we won’t be able to learn any lessons. Thirdly we will never be able to improve the governance of our dams and rivers. Fourthly, we won’t be able to fix accountability.

There is so much at stake related to governance of our dams, but we seem completely unconcerned about it. There is a lot we can learn from others here.

DRP News Bulletin 25 February 2019: Listen, Climate Bonds Initiative: Big Hydro is NOT climate solution

February 25, 2019February 26, 2019 SANDRPLeave a comment

As about 500 global financiers meet in London on March 5-7, 2019, one of the items on agenda pushed by Big Hydro lobby is criteria to include Big Hydro as climate solution. As following Comment in Nature shows, this is completely based on lobbying efforts and not based on merit of the case. If the merits of large hydro were to looked at objectively, there is absolutely no case of inclusion of Large Hydro as climate solution. In fact, the article does not attempt to list the severe, widespread and long lasting adverse social and environmental impacts of large hydro. Today when there is BIG question mark over even economic viability of large hydro, such attempts are clearly uncalled for. Hope the global financiers will see through this lobbying effort.

The World Hydropower Congress will meet in Paris during May 14-16, 2019. Their program says:

Following over two years of discussions with industry, academia, governments and international NGOs, the Climate Bonds Initiative, an investor-focused not-for-profit is due to launch a consultation later this year on proposed green bond criteria for hydropower. This criteria is seen as key to fully unlocking the market to the hydropower sector, as to date it has been held back a lack of clarity over appropriate standards. https://congress.hydropower.org/2019-paris/programme/green-bonds-for-hydropower/

This shows that the Congress, essentially a Hydropower Lobby meeting, is also interconnected with the Climate Bond Initiative on Hydropower.

DRP News Bulletin 1 October 2018: Hungry Water Effect due to Dams & Unsustainable Sand Mining Worsened Kerala Floods

October 1, 2018October 2, 2018 SANDRPLeave a comment

Dams and reservoirs make rivers sediment-starved and menacing manifold downstream. While heavy rainfall is also a key factor behind the floods, hungry water had a more pronounced effect, says D. Padmalal, Scientist and Head, Hydrological process group, National Centre for Earth Science Studies.

– “When the sediment transport is interrupted, the potential energy of the hungry water released from dams will scour the river banks downstream, uprooting trees or riparian vegetation and damaging bridges and other engineering structures,” explains Dr. Padmalal. Overloaded with silt and clay from the eroding river banks, the highly turbid and viscous water clogs drainage channels. Subsequent discharge of water from the dam will lead to inundation and waterlogging of large areas.

– Hungry water can also develop in high gradient river channels devoid of adequate quantity of sand and gravel, especially during periods of high rainfall. “Years of uncontrolled sand mining have left most of the rivers in Kerala depleted or exhausted of sand and gravel. This creates a situation similar to the release of hungry water from dams,” notes Dr. Padmalal. When the river channel has adequate supply of sand and gravel, the potential energy of the water is used to transport the mixture. The water does not scour the banks or turn muddy.

DRP News Bulletin 3 Sept 2018: CHINA HAS STARTED DECOMMISSIONING DAMS

September 3, 2018September 3, 2018 SANDRPLeave a comment

In a mountain village in southwest China’s Sichuan province, authorities have demolished seven small dam projects this year along a river to clear illegal developments in a new nature reserve. The demolition is part of a nationwide programme to close hundreds of tiny and often ramshackle dams and turbines and bring order to China’s massive hydropower sector after years of unconstrained construction.

The dams sat on an unnamed tributary of the fierce and flood-prone Dadu river, which feeds into the Yangtze, Asia’s largest and longest river, where the government says the “irregular development” of thousands of small hydropower projects has wrecked the ecology. But green groups say the campaign will not necessarily save the environment because it will not affect big state hydropower stations, which they say have caused the most damage.

On the 48 km Zhougong, authorities have already demolished small projects built in nature reserves or encroaching upon new “ecological red lines” drawn up to shield a quarter of China’s territory from development.

The government says small dams have disrupted the habitats and breeding patterns of many rare species of fish, although green groups argue the damage wrought by bigger dams is more severe, with entire towns and ecosystems submerged in water, which they say increases the risk of earthquakes, landslides and even climate change.

DRP News Bulletin 25 September 2017 (Three Incidents of Canals & Dam Breach In Two Days, Who Is Responsible?)

September 25, 2017September 25, 2017 SANDRPLeave a comment

This week there have been three incidents of canals and dam breach in three States raising concern over quality of construction of dams and canals in India.

All these incidents are a result of negligence exercised by concerned departments. These incidents also proves that the quality of construction of dams and canals in India is not as par standard.

It is surprising that no government official or private contractor has been held responsible for these avoidable incidents. To avoid recurrence of such incidents, governments of these states bring the involved officials and persons to justice. It also strictly monitor the quality of construction to avoid wastage of public money. The safety of the public is also uncompromising and hence should not rush through the irrigation projects without proper consultation care.
